Wii Fit feels the burn, sells 1 million in Japan

The Wii Fitexercise machine pressure pad has sold one million units in Japan since its Dec. 1 release. And just like the millions of gym memberships left hanging each year, we have to wonder just how many of these things have actually inspired weight loss.

Wii Fitstill doesn't have a US or European release date yet (we're guessing Nintendo has to figure out how to support more than 300 lbs. first), but given Wii's broad demographic, once westernized, Wii Fit could easily become the system's must-have impulse buy – and the first 'game' to actually give us guilt trips.
